Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

The monitoring part of the equipment detection point is the transmission assembly


Combining equipment for point inspection and regular repair, carry out simple diagnosis of main production equipment, equipment on-line monitoring and management of key equipment status maintenance, tendency to manage fault degradation curve drawing of mine crushing equipment status management, comprehensive diagnosis of rotating equipment faults, fault diagnosis of cone crushers, Predict the failure cycle of mining equipment, analyze failure modes, and grasp the probability of failure. Early detection of potential equipment failures, making maintenance decisions, and realizing predictive maintenance of equipment. In recent years, the failure rate has increased, and common failures and sudden failures have increased year by year with the growth of service life. The overhaul is difficult, the overhaul cost is high, and the equipment operation performance is declining year by year. Analysis of the current situation of the moving cone bevel gear cone crusher The type cone crusher is the main production equipment of Lingxiang Iron Mine. Failure mode: The horizontal shaft sleeve is glued, the transmission and the large and small bevel gears are worn and the teeth are broken, the gap between the large copper sleeve of the main shaft is increased, the spherical bush is strained, and the internal failure of the motor. Cone crusher fault diagnosis model analysis fault diagnosis program must be type cone crusher fault diagnosis program is established as shown in the figure, the establishment of the diagnosis part of the fault diagnosis steps, take the cone crusher as an example for diagnosis. The equipment detection point is shown in the figure. The monitoring part is the transmission assembly, and the measurement parameter is the vibration speed. Equipment online monitoring, diagnosis and analysis year and month. The results of the analysis of the cone crusher online monitoring data are listed in the table. The equipment failure fluctuation situation and law, the four monitored data all fluctuate, and the water pressure fluctuation range is large, indicating that the equipment failure is not Independent existence is the interconnection of the internal structure of the host. The results of the frequency spectrum analysis of the vibration velocity of the measuring points of the three equipment No. The equipment No. three side intestines are shown in the figure as the state of the crusher. The internal failure of the host is a complicated factor.

Therefore, the number of measuring points has been intensively monitored, and the frequency spectrum has been used for precise testing and analysis.
